OBJECTIVE Prehospital emergency amputation is a rare procedure, which may be necessary to free a time-critical patient from entrapment. This study aimed to evaluate four techniques of cadaveric lower limb prehospital emergency amputation. METHOD A guillotine amputation of the distal femur was undertaken in fresh frozen self-donated cadavers. A prehospital doctor conducted a surgical amputatio...

Background. In this study, the cut-out risk of Dynamic Hip Screw (DHS) was investigated in nine different positions of the lag screw for two fracture types by using Finite Element Analysis (FEA). Methods. Two types of fractures (31-A1.1 and A2.1 in AO classification) were generated in the femur model obtained from Computerized Tomography images. The DHS model was placed into the fractured femur...

HYPOTHESIS During robotic milling of the temporal bone, forces on the cutting burr may be lowered by choice of cutting parameters. BACKGROUND Robotic bone removal systems are used in orthopedic procedures, but they are currently not accurate enough for safe use in otologic surgery. We propose the use of a bone-attached milling robot to achieve the required accuracy and speed. To design such a...

Objective(s): Scaffolds are considered as biological substitutes in bone defects which improve and accelerate the healing process of surrounding tissue. In recent years a major challenge in biomaterials is to produce porous materials with properties similar to bone tissue. In this study, the natural bioactive hydroxyapatite scaffolds with nano Diopside /Forstrite coating was successfully synthe...

OBJECT The object of this study was to propose an alternative procedure to the classic decompressive hemicraniectomy using an "in-window" craniotomy and a "bridgelike" duraplasty. METHODS The authors performed a large, almost rectangular craniotomy involving the frontal, temporal, and parietal bones and part of the occipital squama in 5 patients. The dura mater is opened and its area is enlar...

The presence of a low level of M protein in the peripheral blood <3gm/dl which is below the required cut off for the diagnosis of plasma cell myeloma is known as monoclonal gammopathy of undetermined significance (MGUS). Elevated levels of serum M protein and detection of M band on serum protein electrophoresis (SPE) can occur in chronic diseases not related to B cell disorders and not always d...

Bone fractures have a high degree of severity. This is usually result the physical trauma diseases that affect bone tissues, such as osteoporosis. Due to its highly vascular nature, in constant state remodeling. Although those younger ages possess bones with regenerative potential, impact disrupted vasculature can severely recovery process and cause osteonecrosis. commonly seen neck femur, scap...

The Misonix BoneScalpel is a novel ultrasonic surgical device that cuts bone and spares soft tissues. This relative selectivity for bone ablation makes BoneScalpel ideally suited for spine applications where bone must be cut adjacent to dura and neural structures. Extensive clinical experience with this device confirms its safety and efficacy in spine surgery. The aim of this report is to descr...

Subjects and Methods The study was based on 33 knees in 30 patients who underwent TKR due to varus osteoarthritis (26 females, 4 males mean age of 69.9 years). All the operations were performed by two of the senior authors (Y.K. and A.K.) using posterior stabilized prostheses. Bone cut in the proximal tibial was made using an extramedullary alignment guide to be perpendicular to the long axis. ...
